Aley Mine Project

Aley Corporation Limited proposes to construct and operate an open-pit niobium mine, located approximately 130 kilometres north of Mackenzie in north-central British Columbia. As proposed, the project would process ten thousand metric tonnes of niobium ore per day, for a total of 94 million tonnes of ore over a mine-life of 27 years.
